Reaction Steps

3.00 g (25.6 mmol) of N-ethyl-3-methoxypropylamine and 1.54 g (25.6 mmol) of acetic acid were placed in a 50 ml two neck flask. While heating the flask in a 90° C. oil bath, 1.08 g (25.6 mmol) of cyanamide was added. After 12 hours of the reaction, the product was purified by a silica gel column chromatography (eluent, chloroform/ethanol=1/2 containing 0.5% acetic acid) to obtain 2.80 g of the title compound (wax-like, 12.8 mmol, 50.0% in yield) in the form of acetate. Results of the analysis of this compound are as follows.
